In the voice of Neil deGrasse Tyson, this episode spins through the cosmos — literally. Planets spin, stars spin, galaxies spin, even black holes drag the fabric of space around with them. Almost nothing in the universe sits still. Why? Has the universe been rotating since the beginning, or is something forcing every object it contains to turn?
The core answer is one of the most beautiful laws in physics: the conservation of angular momentum. When a vast gas cloud collapses to form a star, any faint initial swirl grows faster and faster as the cloud shrinks — the same figure skater effect that spins an ice skater into a blur when she pulls her arms in. That single principle explains accretion disks, spiral galaxies and why the planets all orbit the same way. Then we descend to the quantum level, where particles carry spin that is not really spinning at all, and the mystery deepens again.
And at the largest possible scale, the question turns philosophical: does the universe itself rotate? Its total angular momentum appears to be astonishingly close to zero, which may be the deepest clue of all about how everything began. Subscribe for more journeys where one simple law explains a universe in motion.
